full_spectrogram2pdf combines full_spectrograms images in .jpeg format to a single pdf file.

full_spectrogram2pdf combines full_spectrograms images in .jpeg format to a single pdf file.

Usage

full_spectrogram2pdf(
  keep.img = TRUE,
  overwrite = FALSE,
  parallel = 1,
  path = NULL,
  pb = TRUE
)

Arguments

keep.img: Logical argument. Indicates whether jpeg files should be kept (default) or remove. (including sound file and page number) should be magnified. Default is 1.
overwrite: Logical argument. If TRUE all jpeg pdf will be produced again when code is rerun. If FALSE only the ones missing will be produced. Default is FALSE.
parallel: Numeric. Controls whether parallel computing is applied. It specifies the number of cores to be used. Default is 1 (i.e. no parallel computing).
path: Character string containing the directory path where the sound files are located. If NULL (default) then the current working directory is used.
pb: Logical argument to control progress bar. Default is TRUE.

Value

Image files in pdf format with spectrograms of entire sound files in the working directory.

Details

The function combines spectrograms for complete sound files from the full_spectrograms function into a single pdf (for each sound file).

Examples

if (FALSE) { # \dontrun{
# save sound file examples
data(list = c("Phae.long1", "Phae.long2"))
writeWave(Phae.long1, file.path(tempdir(), "Phae.long1.wav"))
writeWave(Phae.long2, file.path(tempdir(), "Phae.long2.wav"))

full_spectrograms(
  sxrow = 2, rows = 8, pal = reverse.heat.colors, wl = 300,
  it = "jpeg", path = tempdir()
)

# now create single pdf removing jpeg
full_spectrogram2pdf(keep.img = FALSE, path = tempdir())

# check this floder
tempdir()
} # }
